On March 6, 2015, Hu, Huayou; Li, Guodong; Hu, Weiming; Liu, Yun; Wang, Xiang; Kan, Yuhe; Ji, Min published an article.Formula: C11H11NO2 The title of the article was Synthesis of Pyrrolo[2,1,5-cd]indolizines through Dehydrogenative Heck Annelation of Indolizines with Diaryl Acetylenes Using Dioxygen as an Oxidant. And the article contained the following:
A dehydrogenative Heck annelation reaction of indolizine with diaryl acetylene via dual C-H bond cleavage was developed. Oxygen gas was employed as a clean oxidant in this catalysis under base-free conditions. Diarylpyrrolo[2,1,5-cd]indolizines were synthesized with high atom economy. In addition, kinetic isotope experiments provided evidence for C-H bond metalation of the 5-position of the indolizine as the rate-limiting step. The experimental process involved the reaction of Ethyl indolizine-1-carboxylate(cas: 93476-46-1).Formula: C11H11NO2
The Article related to dehydrogenative heck annelation indolizine diaryl alkyne palladium catalyst, pyrroloindolizine diaryl preparation, Heterocyclic Compounds (One Hetero Atom): Indoles, Indolizines, Carbazoles, and Other Arenopyrroles and other aspects.Formula: C11H11NO2
